This is fairly easy. You can find many examples of evolving computer program within the field of evolutionary computing. To start you can go to google scholar and search for "genetic algorithm" (1.9mio hits), or if you prefer an ordering by application domain and specific programs check out the list on wikipedia:
That's not at all what the question was.
I notice you appended "on it's own" to EOM's statement.
No, I didn't do that at all. Read more closely.
This would (strictly speaking!) make your statement true since a computer program "on it's own" presumably would be a computer program without a medium to run it, however this would clearly also be a strawman.
Of course it isn't. I didn't misrepresent his argument or change it. The question was asked very specifically the way it was do demonstrate the teleological error or saying that because programs today must to designed to evolve, then biology must have been also.
Far from a strawman, the whole point of that was to compare and contrast computing technology with biology and highlight the dangers of attempting to retroactively assign meaning and make assumptions about past events based on a completely unrelated event today, particularly when the poster has demonstrated a poor understanding of both.
That could have been a fruitful and engaging discussion has EoM chosen not to abandon it. You simply missed the entire point in your desire to create a "gotcha" moment with me.
BTW, EoM, this is a GREAT example of me making sure I can back up what I post, despite your thoughts otherwise.
